Exercise caution when planning your vacation....I've been guilty of this one...
Don't tip off criminals by detailing all of your vacation plans on the internet.
From Independent Traveler: "In a world where it seems everyone is blabbing about their business on social networking sites like Facebook and Twitter, it's important to stop and think: Who exactly is reading this stuff? The anonymity of the Internet can encourage us to share personal information without fully realizing that there may be hundreds of complete strangers receiving our daily musings. Would you announce to a crowd that you will be leaving your house unattended for two weeks this December? If not, then you should think twice about posting your detailed vacation plans on Twitter or Facebook -- especially if that information is visible to Internet users other than your friends and family (and it probably is). Be careful what you say on your answering machine or voice mail too. Callers don't need to know that you're not home -- they just need to know that you can't come to the phone right now."
